Administrators told her she couldn’t return to school until her hair grew back or she wore a wig, Colorado’s KDVR reports:

Kamryn decided to have a big makeover -- shaving off all of her hair in solidarity with a friend [Delaney] who was starting chemotherapy to treat cancer.

I was really excited I would have somebody to support me and I wouldn't be alone with people always laughing at me. I would at least have somebody to go through it all," says Delaney, who just began chemotherapy.

...

Kamryn's mother emailed the school explaining why she got the extreme haircut, but administrators at first said they couldn't make exceptions."

Notably, the school’s rules also ban lunch boxes with cartoon characters and requires pupils as young as kindergarteners to wear ‘dress-type shoes.’ More than half of the code is addressed only to female students.

Officials told KDVR Kamryn was invited back to school on Tuesday, and that an emergency meeting was called to vote on whether to repeal the rule.
